Description
Beleuchtungsanlage an Kraftfahrzeugen mit einer das Blenden entgegenkommender
Fahrzeuge verhütenden Lichtverteilung
Andererseits wurde beobachtet, daß bei Nebel die starken Scheinwerferstrahlen durch optische Auflösung in den feinsten Wassertröpfchen eine undurchsichtige, leuchtende Wand erzeugen, die das Fahren behindert. Bekanntlich fährt man mit kleinstem Licht bei Nebel besser als mit großem. Es wurde ferner beobachtet, daß bei Nebel diejenigen Bereiche, die nur von einfachen Strahlen getroffen werden, wie die dem Wagen zunächstliegenden Seitenbereiche, gut sichtbar sind, während alle diejenigen Bereiche, in denen sich die Strahlen der regelmäßig angebrachten beiden Scheinweifer kreuzen, für das Auge undurchdringlich werden. Es genügt aber für das sichere Fahren die volle Erkennbarkeit des Bodens, der Seitenränder und der oberen Bereiche, der Bäume, Häuserwände u. dgl. Daraufhin wurden Versuche durchgeführt, welche diese Erkenntnisse bestätigen.On the other hand, it was observed that in fog the strong headlights through optical dissolution in the finest water droplets an opaque, luminous one Create a wall that hinders driving. It is well known that you go with it smallest Light better in fog than with large. It was also observed that in fog those areas that are only struck by simple rays, such as the dem Carriage lying side areas, while all those are clearly visible Areas in which the rays of the regularly attached two shamrocks cross, become impenetrable to the eye. But it is enough for safe driving the full visibility of the bottom, the side edges and the upper areas, the Trees, house walls and the like. Then experiments were carried out, which these Confirm findings.
Es ergibt sich daraus ein vollständig von dem bisher angewandten verschiedenes Verfahren zur Beleuchtung von Fahrzeugen. Dieses besteht darin, daß gerade der Bereich, der bisher hauptsächlich bestrahlt wurde, nämlich der vordere, abgeschirmt wird, so daß entgegenkommende Fahrer auf Autos, Motorrädern und Fahrrädern sowie Fußgänger die Lichtquelle und den direkten Strahlengang des Reflektors nicht sehen, sondern mit ihren Blicken nur noch mit einem gewissen Winkel die auftretenden Strahlenbündel der Scheinwerfer schneiden, die nur nach unten, nach oben und nach der der Fahrbahn abgewandten Seite gerichtet sind. Die mittleren Bereiche werden durch Diffusion des Lichtes aus den allseitigen Strahlenbündeln ausreichend erhellt.The result is something completely different from what has been used up to now Method for lighting vehicles. This consists in the fact that precisely the area which has so far mainly been irradiated, namely the front one is shielded, so that oncoming drivers on cars, motorcycles and bicycles as well as pedestrians rather than seeing the light source and the direct beam path of the reflector with their gazes the bundles of rays that appear only at a certain angle the headlights cut just down, up and down the roadway facing away from the side. The middle areas are made by diffusion of the light from the all-round bundles of rays is sufficiently illuminated.
Entgegenkommende Fahrzeuge sind nach Breite durch die zweckmäßig auf den Außenseiten ((Kotflügeln) aufgesetzten Unten- und Rechtsscheinwerfer und nach Höhe durch den Obenscheinwerfer zu erkennen, wobei man im Gegensatz zu bisher die Scheinwerfer selbst nicht oder nur wenig, statt dessen aber die austretenden Lichtbündel sieht.Oncoming vehicles are expediently based on the width the outer sides ((fenders) attached lower and right headlights and after Height to be recognized through the top headlight, whereas in contrast to previously the Headlights themselves not or only a little, but instead the emerging light bundles sees.
Zur Durchführung des Verfahrens braucht man neuartige Bauarten und Anordnungen von Scheinwerfern, da die -bisherigen fest eingebauten aller Typen die erforderliche Einstellung nicht gestatten.To carry out the process you need new types and Arrangements of headlights, as the previous permanently installed of all types Do not allow required setting.
Lediglich der linke Scheinwerfer kann mit der üblicherweise vorgesehenen Einstellungsmöglichkeit unter der Waagerechten passend eingestellt werden. Der rechte muß im Winkel nach rechts derart gerichtet sein, daß die linke Strahlenbegrenzung äußerst in die Fahrtrichtung weist.Only the left headlight can be used with the one usually provided Setting option below the horizontal can be set appropriately. The right one must be directed at an angle to the right in such a way that the left beam limit points extremely in the direction of travel.
Wenn auch diese Ausführung schon einen erheblichen Fortschritt bringt und beispielsweise eine Verdoppelung der Fahrtgeschwindigkeit 'bei Nebel gestattet, ist sie doch nicht voll befriedigend. Zur einwandfreien Lösung müssen ziemlich eng gestellte Leitflächen, die aber deshalb nur geringe Tiefenausdehnung haben brauchen, in der Richtung des Strahlenaustritts am Reflektor (falls dieser beweglich, mit diesem fest verbunden), angebracht werden, welche die Lichtstrahlen nur in der Achsenrichtung des Reflektors durchlassen und bei Schrägstellung den Einblick in die Reflektorflächen und die Lichtquelle verwehren. Die Längskanten der nach unten gerichteten Leitflächen des linken Scheinwerfers stehen dabei waagerecht, die Kanten der Leitflächen des nach rechts gerichteten rechten Scheinwerfers senkrecht.Even if this implementation already brings considerable progress and, for example, a doubling of the speed of travel 'allowed in fog, it is not completely satisfactory. For a perfect solution you have to be pretty tight provided guide surfaces, which therefore only need a small depth, in the direction of the beam exit at the reflector (if this is movable, with firmly connected to this), which the light rays only in the axial direction of the reflector and, if it is inclined, the view into the reflector surfaces and block the light source. The long edges of the downward facing baffles of the left headlight are horizontal, the edges of the guide surfaces of the right headlight vertical.
Vollkommen wird die Einrichtung durch einen dritten auf dem Dach oder Verdeck über Augenhöhe des Fahrers angebrachten Scheinwerfer, der schräg nach oben gerichtet ist, mit entsprechenden Leitflächen, die wiederum horizontale Längskanten haben. Mit einer solchen Einrichtung kann man ohne Biluxlampen fahren; man braucht beim Begegnen mit anderen Wagen nicht abzublenden, weil diese in keiner Weise behelligt werden. iMan fährt bei jeder Witterung, auch strömendem Regen und dichtestem Nebel sicher und viel schneller, als dies mit allen bisher bekannten Anordnungen möglich war.The facility is completed by a third on the roof or Canopy above the driver's eye level, the headlights are mounted diagonally upwards is directed, with corresponding guide surfaces, which in turn have horizontal longitudinal edges to have. With such a device one can drive without bilux lamps; one needs Not to be dimmed when encountering other cars, because they are not bothering you in any way will. iMan drives in all weather conditions, including pouring rain and thick fog safely and much faster than is possible with all previously known arrangements was.
